Cognee ROCKS! Keep the work guys, its amazing. Im currently building an app and the graph layer is on top of Cognee. The fact that i can build my own KGs logics, how to create, how to retrieve, the vectors... is amazing. I will be using multiple pipelines and so far Cognee is the most capable of it.
@DiscordUser
thanks, you guys are great always responding and ontop of it.
@bsenftner
My research: Cognee being a functional & lowered expense leader in graph rag tech.
@DiscordUser
Cool project! The idea of dynamically evolving knowledge graphs for memory makes a lot of sense, especially for handling complex dependencies in codebases.
@DiscordUser
thank you 🙏🏼 for creating such an innovative open-source tool!
@DiscordUser
… cognify managed to build an amazing graph out of it and my question got answered right away.
@DiscordUser
Future of Enterprise grade AI Agents depends on the information infrastructure. Building agents on symbolic architecture is a key requirement for multi agent system for which abstraction provided by Cognee is a MUST to have .. Great Job Folks !!
@DiscordUser
Your guidance is much appreciated. Thank you to the Cognee team's amazing work.

We tried understanding the proximity and relationships of our users before, but SQLs got out of hands and embeddings were too sparse. With cognee, we managed to get a POC done in 2 days on 40 000 students from Bremen.

Guys helped me to build a custom knowledge base of building codes and regulations that I just had to upload and it all worked. I could easily query the knowledge and update it with new regulations. This has significantly streamlined my workflow and decision-making process.
